In-body massage device Cross-reference to related applications

[0001] This disclosure claims priority to the following patent application: Chinese Patent Application No. CN202520741868.0, filed on April 17, 2025. Technical Field

[0002] This application relates to an in-body massage device. Background Technology

[0003] In the field of immersive massage, existing massage devices typically include stimulation structures to stimulate external areas of the body. However, these stimulation structures are fixed and difficult to adapt flexibly to the diverse characteristics of the areas to be massaged. For example, in women's anatomy, there are significant individual differences between the external and internal areas to be massaged. Using a fixed stimulation structure often fails to provide effective stimulation to these external areas in a suitable posture during actual use, greatly impacting the user experience. Summary of the Invention

[0004] This invention was made in response to the problems mentioned above.

[0005] According to one aspect of the present invention, an in-body massage device includes: a massage body, a portion of which is insertable into a user's body to be massaged; and a stimulation structure located on one side of the massage body and connected to the massage body, the stimulation structure being for contacting the user's external body to be massaged. The massage body includes a housing, at least one side of which has a through-hole. The stimulation structure includes a stimulating body and a position adjustment assembly. A portion of the position adjustment assembly is movably connected to the massage body within the cavity of the massage body, and another portion of the position adjustment assembly protrudes outside the massage body via the through-hole and is detachably connected to the stimulating body. The length of the through-hole in the length direction of the massage body is greater than the length of the portion of the position adjustment assembly protruding from the through-hole in that length direction. The stimulating body is subjected to at least one of translation and rotation under an external force applied by the user. When the stimulating body rotates, it causes the protruding portion of the position adjustment assembly to rotate within the through-hole. When the stimulating body translates, it causes the protruding portion of the position adjustment assembly to translate within the through-hole.

[0006] Furthermore, in the above-mentioned in-body massage device, the position adjustment assembly includes: a connecting body, one end of which is disposed in the inner cavity of the massage body, and the other end which protrudes to the outside of the massage body through the communicating hole and is detachably connected to the stimulating body; two connecting portions, which are disposed on opposite sides of the connecting body along the second axis and move synchronously with the connecting body; and two position adjustment portions, which are coaxially connected to the respective of the two connecting portions. The two position adjustment portions have opposite first ends and second ends, the first ends being connected to the two connecting portions, and the second ends being connected to the massage body through the respective of the two horizontal limiting holes. When the stimulating body translates, the stimulating body drives the two position adjustment portions to translate in the respective of the two horizontal limiting holes. When the stimulating body rotates, the stimulating body drives the two connecting portions to rotate relative to the respective of the two position adjustment portions about the second axis.

[0007] Furthermore, in the above-mentioned in-body massage device, the outer shell has a first wall and a second wall defining the width of the horizontal limiting hole. The first wall and the second wall are formed extending along the first axis and are opposite to each other and parallel in a direction perpendicular to the first axis and the second axis. The length of the connecting hole in the length direction of the massage body is greater than the length of the horizontal limiting hole in that length direction. The second end has a first abutting surface and a second abutting surface. The first abutting surface and the second abutting surface are opposite to each other and parallel. The length of the first abutting surface and the second abutting surface in the first axis is less than the length of the first wall and the second wall. The first abutting surface abuts against the first wall, and the second abutting surface abuts against the second wall.

[0008] Furthermore, in the above-mentioned in-body massage device, when the first abutting surface and the first wall surface are in mutual engagement and / or the second abutting surface and the second wall surface are in mutual engagement and connection, the horizontal position of the two position adjustment parts relative to the massage body remains unchanged; when the two connecting parts and the respective first ends of the two position adjustment parts are in mutual engagement and connection, the rotational position of the two position adjustment parts relative to the massage body remains unchanged.

[0009] Furthermore, in the above-mentioned in-body massage device, the connecting part is a gear, the first end is a gear ring, the first end is sleeved on the outer side of the connecting part, the outer diameter of the connecting part and the inner diameter of the first end are matched and meshed, and relative rotation is achieved by alternating and repeatably meshing and disengaging the connecting part and the first end.

[0010] Furthermore, in the above-mentioned in-body massage device, one of the first end and the connecting part is formed as a cylindrical structure, and the other is formed as an annular structure. The annular structure is sleeved on the outer side of the cylindrical structure. The inner circle size of the annular structure matches the size of the cylindrical structure. The inner surface of the annular structure is uniformly arranged with a plurality of recesses and / or protrusions. The outer side of the cylindrical structure is uniformly arranged with a plurality of protrusions and / or recesses that match the shapes of the plurality of recesses and / or protrusions on the inner surface of the annular structure. When the first end and the connecting part are mutually connected, when the first end and the connecting part rotate relative to each other by a certain angle, the first end and the connecting part are misaligned. When they continue to rotate relative to each other by a certain angle, the first end and the connecting part reconnect.

[0011] Furthermore, in the above-mentioned in-body massage device, the position adjustment assembly further includes two locking members. The two locking members are respectively connected to the ends of the two position adjustment parts away from the connecting body and protrude toward the outer side of the two position adjustment parts. The outer diameter of the two connecting parts is larger than the outer diameter of the two position adjustment parts. A first receiving groove is formed around the two horizontal limiting holes in the outer surface of the housing. The first receiving groove is recessed from the outside of the housing toward the inner cavity of the housing for the locking members to abut and move. A second receiving groove is formed around the two horizontal limiting holes in the inner surface of the housing. The second receiving groove is recessed from the inner cavity of the housing toward the outside of the housing for the connecting parts to abut and move. The horizontal limiting holes extend from the bottom surface of the first receiving groove to the bottom surface of the second receiving groove, connecting the first receiving groove and the second receiving groove.

[0012] Furthermore, in the aforementioned in-body massage device, the position adjustment assembly includes a first electrical connection structure, a portion of which protrudes from the communicating hole.

[0030] Referring to Figures 1 to 10, the insertable massage device 100 of this application is illustrated. The massage body 10 is integrally formed into an elongated columnar structure, including an insertion part 200 and a handle part 400. The insertion part 200 extends in an elongated columnar shape and is used to insert into the user's body at a site to be massaged, such as an acupoint. The insertion part 200 may include at least one of a vibration motor, a telescopic motor, and a swinging structure to achieve functions such as vibration, telescopic movement, and swinging movement. The handle part 400 facilitates user grip and operation.

[0031] This in-body massage device 100 includes a massage body 10 and a stimulation structure 30 that are interconnected.

[0032] The massage body 10 includes a housing 101, with a through hole 10a formed on at least one side of the housing 101. The stimulation structure 30 includes a stimulator 600 and a position adjustment assembly 800. At least a portion of the position adjustment assembly 800 is movably connected to the massage body 10 within the inner cavity 110 of the massage body 10, and another portion of the position adjustment assembly 800 is exposed outside the massage body 10 via the through hole 10a and detachably connected to the stimulator 600. The length LH1 of the through hole 10a in the longitudinal direction of the massage body 10 is greater than the length LH2 of the portion of the position adjustment assembly 800 exposed in the through hole 10a in that longitudinal direction. The stimulator 600 can be translated or rotated under the external force applied by the user. When the stimulator 600 rotates, it causes the exposed portion of the position adjustment assembly 800 to rotate within the through hole 10a. When the stimulator 600 translates, it causes the exposed portion of the position adjustment assembly 800 to translate within the through hole 10a.

[0033] The massage body 10 includes a housing 101 and a first flexible material layer 103 covering the outer surface of the housing 101. The shape of the housing 101 conforms to the overall shape of the insertion portion 200 and the handle portion 400. A through hole 10a is formed in at least one side of the housing 101 near the insertion portion 200 (e.g., the middle of the housing 101), and the through hole 10a communicates with the cavity of the housing 101. Two symmetrically arranged mounting portions K are formed on two symmetrical sides of the housing 101. Each mounting portion K includes a horizontal limiting hole K2 extending through the sidewall of the housing 101 and along a dummy first axis L1. The first axis L1 is the same as or substantially the same as the length direction of the massage body 10 (housing 101). On a dummy second axis L2 perpendicular to the first axis L1, the two horizontal limiting holes K2 are arranged on opposite sides of the through hole 10a such that the through hole 10a is sandwiched between the two horizontal limiting holes K2. Two horizontal limiting holes K2 communicate with the connecting hole 10a via the inner cavity 110 of the housing 101. Each of the two mounting portions K has a first wall surface K21 and a second wall surface K22 defining the width of the horizontal limiting hole K2. The first wall surface K21 and the second wall surface K22 extend along a first axis L1, are opposite each other, and are parallel. The first wall surface K21 and / or the second wall surface K22 are formed as toothed surfaces or microstructured surfaces with protrusions and / or recesses. The second axis L2 is perpendicular to the first axis L1. In other embodiments, the microstructured surfaces may be formed separately and fixed to the first wall surface K21 and the second wall surface K22 by adhesives. Furthermore, this application can also be formed with a structure having two stimulators 600 extending from their respective separate connecting holes 10a. These two stimulators 600 can be connected to the same position adjustment assembly 800 for joint position adjustment, or they can be connected to different position adjustment assemblies 800 for individual position adjustment.

[0034] The position adjustment assembly 800 is partially housed in the inner cavity 110 of the housing 101 and installed in the horizontal limiting holes K2 of the two mounting portions K. The position adjustment assembly 800 is used to connect the stimulator 600 and the housing 101. The position adjustment assembly 800 is disposed in the inner cavity 110 of the housing 101 in such a way that it is movably installed on both sides in the horizontal limiting holes K2 of the two mounting portions K. It moves in contact with the first wall surface K21 and the second wall surface K22, thereby being movably connected to the housing 101. The position adjustment assembly 800 protrudes from the connecting hole 10a and is detachably connected to the stimulator 600. A portion of the position adjustment assembly 800 is housed in the inner cavity 110 of the massage body 10 and connected to the massage body 10 on opposite sides. Another portion protrudes to the outside of the massage body 10 via the connecting hole 10a and is detachably connected to the stimulator 600. Since the length LH1 of the connecting hole 10a in the length direction (which is also the first axis L1) of the massage body 10 is greater than the length LH2 of the part of the position adjustment component 800 exposed from the connecting hole 10a in the length direction of the massage body 10, the position adjustment component 800 can move and rotate in the connecting hole 10a along the length direction of the connecting hole 10a.

[0035] Furthermore, when the stimulator 600 has electronic components, the position adjustment assembly 800 may be provided with a first electrical connection structure 870, and the stimulator 600 may be provided with a second electrical connection structure 650. When the position adjustment assembly 800 is connected to the stimulator 600, the first electrical connection structure 870 and the second electrical connection structure 650 come into contact and are electrically connected.

[0036] The stimulator 600 is positioned above the connecting hole 10a and may contain at least one of a vibration motor, a telescopic motor, a negative pressure generating unit, or a tapping structure for contacting the external area to be massaged. The stimulator 600 may also include a second flexible material layer 500 covering its outer surface, which is made of a flexible material. The first flexible material layer 103 and the second flexible material layer 500 are sandwiched together in the gap between the outer shell 101 and the stimulator 600, which surrounds the connecting hole 10a, preventing water, foreign objects, etc., from entering the inner cavity 110 of the outer shell 101 even when the stimulation structure 30 moves.

[0037] The stimulator 600 and the position adjustment assembly 800 move together and have at least two degrees of freedom, including a translational degree of freedom on the first axis L1 and a rotational degree of freedom on the second axis L2. The stimulator 600 and the position adjustment assembly 800 can translate along the first axis L1 to adjust their translational position relative to the housing 101, and can rotate along the second axis L2 to adjust their rotational position relative to the housing 101. The second axis L2 is perpendicular to the first axis L1 and passes through the horizontal limiting hole K2 of each mounting portion K. Opposite sides of the second axis L2 of the position adjustment assembly 800 are movably connected to the housing 101.

[0038] The position adjustment assembly 800 includes a connecting body 860, a first electrical connection structure 870, and two connecting portions 810, two position adjustment portions 830, and two locking members 840 respectively connected to both sides of the connecting body 860. Here, the second shaft L2 is defined as the arrangement direction of the two connecting portions 810, and also the arrangement direction of the two position adjustment portions 830 and the two locking members 840.

[0039] The connecting body 860 extends along a direction intersecting or perpendicular to the first axis L1 and perpendicular to the second axis L2. One end of the connecting body 860 is mounted in the inner cavity 110 of the housing 101, and the end face of the other end exposes a portion of the first electrical connection structure 870. The other end of the connecting body 860 with the first electrical connection structure 870 is exposed from the connecting hole 10a for detachable mounting and electrical connection of the stimulator 600.

[0040] Two connecting portions 810 extend vertically along the second axis L2, respectively, on opposite sides of the connecting body 860, and are fixedly connected to the connecting body 860. For example, the two connecting portions 810 are integrally formed with the connecting body 860. Thus, the two connecting portions 810 move synchronously with the connecting body 860. The connecting portion 810 can be a gear or a gear ring.

[0041] Two position adjustment portions 830 are coaxially connected to two connecting portions 810, respectively. Each position adjustment portion 830 includes a first end 831 and a second end 833 opposite to each other. The first end 831 can rotate about a second axis L2, thereby adjusting its rotational position relative to the connecting body 860. The second end 833 contacts the mounting portion K and can translate along the first axis L1, thereby adjusting its position in the two mounting portions K, i.e., adjusting its horizontal position relative to the housing 101. If the connecting portion 810 is a gear, the first end 831 is a gear ring; if the connecting portion 810 is a gear ring, the first end 831 is a gear. The gear ring is fitted onto the outer surface of the gear, and the two are meshed together in a size-matched manner. The outer diameters of the two connecting portions 810 are larger than the outer diameters of the two position adjustment portions 830, allowing the connecting portions 810 to abut against the inner surface of the housing 101. The first end 831 and the connecting portions 810 are meshed together, so that without external force, the first end 831 and the connecting portions 810 remain engaged and their relative rotational positions remain unchanged.

[0042] Furthermore, the horizontal limiting hole K2 can be set such that its length in the longitudinal direction of the massage body 10 is less than the length LH1 of the connecting hole 10a. Therefore, even if the second end 833 moves to either side of the horizontal limiting hole K2, the connecting body 860 connected to the second end 833 can still deflect towards that side until it abuts against the end of the connecting hole 10a on that side. Thus, the adjustable range of the stimulator 600 can be increased. Of course, this application is not limited to this; the length of the horizontal limiting hole K2 is not less than the length LH1 of the connecting hole 10a, and can be set according to actual needs.

[0043] As shown in Figure 8, when using the in-body massage device 100 of this application and needing to massage the user's external massage area A, it is assumed that the external massage area A is located below and in front of the surface of the stimulator 600 where stimulation can be applied. At this time, an external force is applied to the stimulator 600 to rotate around one side L21 of the second axis L2. With the first end 831 and the connecting part 810 engaged and connected, after applying the external force to the stimulator 600, the first end 831 and the connecting part 810 alternately and repeatedly engage and disengage and engage with each other. As shown in Figure 9, the relative rotational position of the stimulation structure 30 (stimulator 600) and the massage body 10 changes from angle θ1 to θ2. The stimulation structure 30 rotates around one side L21 of the second axis L2 to a position that contacts the external massage area A. Then, the external force is removed, and the first end 831 and the connecting part 810 maintain the changed relative rotational position. The aforementioned misalignment refers to the deviation between the tips and grooves of the teeth of the first end 831 and the connecting portion 810. Depending on the position of the external massage area, the relative rotational position of the stimulation structure 30 and the massage body 10 is appropriately adjusted to ensure that the stimulation body 600 contacts the external massage area A.

[0044] Furthermore, the first end portion 831 and the connecting portion 810 of this application may not be connected by meshing teeth. For example, one of the first end portion 831 and the connecting portion 810 may be formed as a cylindrical structure with a plurality of recesses and / or protrusions evenly arranged on its outer surface, and the other may be formed as an annular structure. The inner diameter of the annular structure matches and meshes with the outer diameter of the cylindrical structure, and the inner surface of the annular structure is evenly arranged with a plurality of protrusions and / or recesses that match the shapes of the recesses and / or protrusions on the outer surface of the cylindrical structure. When the first end portion 831 and the connecting portion 810 are in a mutually engaged state, if the first end portion 831 and the connecting portion 810 rotate relative to each other by a certain angle, the originally mutually engaged recesses and protrusions will be misaligned, resulting in a misaligned state. If the multiple recesses and protrusions re-engage and the external force is removed when the rotation continues by a certain angle, the first end portion 831 and the connecting portion 810 will remain mutually engaged and their changed relative rotational positions will remain unchanged.

[0045] The second end portion 833 has a first abutment surface 8331 and a second abutment surface 8333 that are opposite to each other. The first abutment surface 8331 and the second abutment surface 8333 are formed opposite to each other and extend parallel to the first axis L1. The second end portion 833 is located in the horizontal limiting hole K2 of the mounting portion K. The first wall surface K21 and the second wall surface K22 are opposite to each other in a direction perpendicular to the first axis L1 and the second axis L2. The first abutment surface 8331 abuts against the first wall surface K21, and the second abutment surface 8333 abuts against the second wall surface K22. The lengths of the first abutment surface 8331 and the second abutment surface 8333 on the first axis L1 are less than the lengths of the first wall surface K21 and the second wall surface K22. At least one pair of the first abutment surface 8331 and the first wall surface K21, and the second abutment surface 8333 and the second wall surface K22, are mutually engaged and connected. For example, the first abutment surface 8331 and / or the second abutment surface 8333 are formed to match the toothed surface or the surface shape of the corresponding first wall surface K21 / second wall surface K22. Therefore, without the application of external force, the relative horizontal positions of the first abutment surface 8331 and the first wall surface K21, and the second abutment surface 8333 and the second wall surface K22, which are mutually connected, remain unchanged.

[0046] The stimulator 600 also includes a first housing 610 and a second housing 630.

[0047] The first housing 610 is designed to contact an external massage area of ​​the human body and can be fitted with at least one of a vibration motor, a telescopic motor, a negative pressure generator, or a tapping structure. The first housing 610 has an inner cavity, for example, shaped like a pocket, a lip, or a tongue. The second electrical connection structure 650 is installed within the inner cavity of the first housing 610. The second housing 630 is fixedly connected to the first housing 610, for example, covering the inner cavity of the first housing 610. The second housing 630 covers the communicating hole 10a of the outer housing 101, and has, for example, a engaging groove for engaging the connecting body 860 on the side facing the communicating hole 10a, and is detachably connected to the connecting body 860. A through hole is formed in the second housing 630, through which the second electrical connection structure 650 is electrically connected to the first electrical connection structure 870.

[0048] As shown in Figure 8, when using the in-body massage device 100 of this application and needing to massage the user's external massage area B, it is assumed that the external massage area B is located in front of the surface to which the stimulator 600 can apply stimulation. At this time, an external force is applied to the stimulation structure 30 to translate along one side L11 of the first axis L1. Since the second end 833 is in contact with the mounting part K, and its first abutment surface 8331 and second abutment surface 8333 are respectively engaged with the first wall surface K21 and the second wall surface K22 of the horizontal limiting hole K2 of the mounting part K, after the external force is applied, the second end 833 will translate along one side L11 of the first axis L1 in the mounting part K. During the translation process, these cooperating structures will alternately and repeatedly engage and disengage and re-engage. For example, when the first abutment surface 8331 is a toothed surface and engages with the toothed surface of the first wall surface K21, with translation, a deviation will occur between the tooth tip and the tooth groove, i.e., engagement misalignment, and continued translation will re-engage. In this way, the stimulation structure 30 can be translated along one side L11 of the first axis L1 until the stimulation body 600 contacts the external massage area B. As shown in Figure 10, once the appropriate position is reached, the external force is removed, and the stimulation structure 30 remains in that position, achieving proper contact with the external massage area B.

[0049] In practical applications, it is often necessary to comprehensively adjust the first axis L1 and the second axis L2 to make the stimulator 600 fit better with the external area to be massaged. By adjusting the translation along the first axis L1 and the rotation angle around the second axis L2, the stimulator 600 can be made to fit the external area to be massaged in the best posture, thus achieving an efficient and comfortable massage experience.

[0050] Two locking members 840 are respectively connected to the ends of the two position adjustment parts 830 away from the connecting body 860, and protrude toward the outer side of the position adjustment part 830, thereby abutting against the outer surface of the housing 101.

[0051] Each of the two mounting portions K may also have a first receiving groove K1 and a second receiving groove K3. The first receiving groove K1 is formed around two horizontal limiting holes K2 in the outer surface of the housing 101, and the first receiving groove K1 is recessed from the outside of the housing 101 toward the inner cavity 110 of the housing 101, for the locking member 840 to abut and move. The second receiving groove K3 is formed around two horizontal limiting holes K2 in the inner surface of the housing 101, and the second receiving groove K3 is recessed from the inner cavity 110 of the housing 101 toward the outside of the housing 101, for the connecting portion 810 to abut and move. That is, the horizontal limiting holes K2 are formed by penetrating a portion of the bottom surface of the first receiving groove K1 to the bottom surface of the second receiving groove K3. In this way, the locking member 840 and the connecting portion 810 clamp the housing 101 by abutting against the inner and outer sides of the housing 101 respectively, thereby stabilizing the movement of the position adjusting assembly 800 in the horizontal limiting holes K2.

[0052] Furthermore, it is understood that as long as the position adjustment component 800 is stable, the locking component 840, as well as the first receiving slot K1 and the second receiving slot K3, can be omitted.

[0053] According to the above embodiments, the stimulator 600 can translate and rotate relative to the outer shell along different axes (L1 and L2), enabling it to flexibly adapt to human physiological characteristics and improve the accuracy and comfort of the massage.
